Structural example of American type cable branch box

If the cable junction box cannot be placed due to the site limitation, it can be directly combined by the cable connector to form a multi-channel cable branch (no bus is required, see the following example for connection method) and placed in the cable trench or other places. Example 1: Four incoming and outgoing lines (2x600A+2x200A)

Each group consists of two T-II cable connectors, three elbow connectors and one intermediate connector. T-II cable connector 200A side is connected with elbow cable connector (the other side is connected with fully insulated oxide arrester).
